O AGC Adjustment (SERVICE 1)
1) Connect RF signal (70dB!0.2dB) and turn on the TV.¡ Standard adjustment Channel
- EU 05 Ch. (frf = 175.25MHz) 2) Press the OK buttons on TV set and Remote Controller at the
same time to get into SVC-0 mode.3) Press the Channel UP/DOWN button on the Remote
Controller several times to find AGC??.4) Press the Volume UP/DOWN button until the AGC Voltage is
the same as the Table below.5) Press the OK(V) button to memorize the data.
O FOCUS Adjustment
1) Tune the TV set to receive a PAL 05CH.2) Adjust the Focus Volume of FBT for best focus.
O Screen Voltage Adjustment
1) Connect the probe of oscilloscope to the RK (Red Cathode)of CPT Board.
2) Set the oscilloscope to 50V/div and 20Us/div and afterputting GND line upon the lowest grid line of the scope bypressing GND button,enter into DC mode.
3) Tune the TV set to receive a PAL-B/G 05CH.4) Adjust Screen Volume of FBT so that the waveform is the
same as below figure (DC 140!3V).
O White Balance Adjustment.(LINE SVC-0)
NOTE : This adjustment should be performed after screen voltageadjustment.
1) Tune the TV set to receive an 100% white pattern.2) Press OK(V) buttons on TV set and remote controller at the
same time to get into SVC mode.3) Press Yellow button on remote controller. (Standard mode)4) Press Channel UP/DOWN button for desirous function
adjustment.5) Adjust VOL+ or VOL-button in each status of "RG--"/"BG--" for
X=272!8, Y=288!8 with color analyzer.(Europe Model:X=288!8, Y=295!X=272!8, 11,000K)
7) Press the OK(V) button to memorize the data.

O Deflection Data Adjustment (Line SVC-1)
NOTE: To enter SVC mode, press "OK" buttons on both TV setand the Remote control at the same time.
1. Preparation for Deflection Adjustment 1) At SVC mode, press the Yellow colored button.
And then, deflection data adjustment OSD (SVC1 mode) willbe displayed.
2) Tune the TV set to receive a PAL 05 CH and set the ARCmode is standard.
2. Deflection Initial Setup Data
3. Deflection Adjustment Procedure
VL (Vertical Linearity)Adjust so that the boundary line between upper and lower halfis in accord with geometric horizontal center of the CPT.
VA (Vertical Amplitude)Adjust so that the circle of a digital circle pattern may belocated within the effective screen of the CPT.
SC (Vertical “S” Correction)Adjust so that all distance between each horizontal lines areto be the same.
VS (Vertical Shift)Adjust so that the horizontal center line of a digital circlepattern is in accord with geometric horizontal center of theCPT.
HS (Horizontal Shift)Adjust so that the vertical center line of a digital circle pattern isin accord with geometric vertical center of the CPT.
Press the OK(V) button to memorize the data.
